As established in his memorandum dated September 14, 2007, the Secretary has determined that applicants for, and holders of, a Department of Energy (DOE) Q or L access authorization (security clearance) will be in Testing Designated Positions (TDP) as specified in DOE Order 3792.3, Drug-Free Federal Workplace Testing Implementation Program, for Federal employees, and Title 10, Code of Federal Regulations, Part 707, Workplace Substance Abuse Programs at DOE Sites, for contractor employees. Accordingly, individuals who are either in, or are selected for, a TDP are subject to applicant, random and "for cause" testing. Additionally, the Secretary has determined individuals who have used illegal drugs within 12 months preceding their completion of a Questionnaire for National Security Positions (QNSP) will be disqualified from further consideration for a security clearance, until such time as they can demonstrate non-use of illegal drugs for 12 consecutive months.
